Nickel nitrate is the inorganic compound Ni(NO 3) 2 or any hydrate thereof. In the hexahydrate, the nitrate anions are not bonded to nickel. Other hydrates have also been reported: Ni(NO 3) 2. 9H 2 O, Ni(NO 3) 2. 4H 2 O, and Ni(NO 3) 2. 2H 2 O. [3] It is prepared by the reaction of nickel oxide with nitric acid: NiO + 2 HNO 3 + 5 H 2 O → Ni ...
No mineral of the ideal Cu(NO 3) formula, or the hydrates, are known. Likasite, Cu 3 (NO 3)(OH) 5 ·2H 2 O and buttgenbachite, Cu 19 (NO 3) 2 (OH) 32 Cl 4 ·2H 2 O are related minerals. [21] [22] Natural basic copper nitrates include the rare minerals gerhardtite and rouaite, both being polymorphs of Cu 2 (NO 3)(OH) 3.
In the NO − 3 anion, the oxidation state of the central nitrogen atom is V (+5). This corresponds to the highest possible oxidation number of nitrogen. Nitrate is a potentially powerful oxidizer as evidenced by its explosive behaviour at high temperature when it is detonated in ammonium nitrate (NH 4 NO 3), or black powder, ignited by the shock wave of a primary explosive.
That is, in grams, the atomic weight of the element divided by the usual valence. [2] For example, the equivalent weight of oxygen is 16.0/2 = 8.0 grams. For acid–base reactions, the equivalent weight of an acid or base is the mass which supplies or reacts with one mole of hydrogen cations (H +).
The solution has 1 mole or 1 equiv Na +, 1 mole or 2 equiv Ca 2+, and 3 mole or 3 equiv Cl −. An earlier definition, used especially for chemical elements , holds that an equivalent is the amount of a substance that will react with 1 g (0.035 oz) of hydrogen , 8 g (0.28 oz) of oxygen , or 35.5 g (1.25 oz) of chlorine —or that will displace ...
The tetrahydrate consists of discrete, octahedral [(H 2 O) 4 Co(NO 3) 2] molecules. The hexahydrate is better described as hexaaquacobalt(II) nitrate, [Co(OH 2) 6][NO 3] 2, as it consists of discrete [Co(OH 2) 6] 2+ and [NO 3] − ions. [5] Above 55 °C, the hexahydrate converts to the trihydrate and at higher temperatures to the monohydrate. [2]
The compound Bi 6 O 5 (OH) 3 (NO 3) 5 ·3H 2 O (equivalent to 6Bi 2 O 3 ·5N 2 O 5 ·9H 2 O) also contains the octahedral units but this time they are joined to form {[Bi 6 O 5 (OH) 3] 5+} 2. [12] Additionally some oxynitrates have layer structures (a common motif also found in bismuth(III) oxyhalides): Bi 2 O 2 (OH)NO 3 (equivalent to BiONO 3 ...
A nitrate nitrite, or nitrite nitrate, is a coordination complex or other chemical compound that contains both nitrite (NO − 2) and nitrate (NO − 3) anions.They are mixed-anion compounds, and they are mixed-valence compounds.
